"Let the joy I experienced spread in the world," says Tirumular in Tirumandiram. That pretty much sums up the decision to transcribe and edit the lecture series on Siva samhita by Kathirasan K. Although the knowledge of Self has to be learnt directly from a teaching this first ever exposition on the first chapter of the Siva Samhita will be very beneficial for the seekers. The chapter is unique as it explains how a seeker can attain total freedom by understanding his true nature. The chapter is also priceless because it organizes the leaching of Sanatana Dharma head of explaining the nature of Self. Kathirasan has explained each verse in detail and supported the teachings with references from Upanishads Bhugavad Gita and other Vedanta texts. The communication style is also simple making it easy for a reader and seeker to understand the meaning of this great text. My respects to the teaching tradition starting from [mm to the anonymous author of Siva samhita to Kathirasan that has made this knowledge available to seekers. I am also grateful to the Hindu Centre, Singapore, under whose aegis these lectures took place in 2010-2011.
